Diagnosis.
This species can be distinguished from the next new species
D. galbinea
sp. nov.
, by the forewing which has the orange-white antemedian band strongly broadened toward costa in the anterior half, and a small orange-white costal patch, a remnant of the postmedian band; the hind wing evenly orange white. The male genitalia can be distinguished from those of
D. galbinea
sp. nov.
by the cucullus without median ridge.
Description.
Male (
Fig. 2A
). Wingspan 21.0 mm.
Head
: Pale orange dorsally. Antenna as long as forewing; basal segment elongated, broadened distally, pale orange dorso-anteriorly and dark brown on posterior surface; flagellum pale orange throughout, without distinct annulations, finely ciliate. Second palpomere of labial palpus thickened, arched, fuscous in basal 1/3, then yellowish brown on outer surface, yellowish white on inner surface; 3
rd
palpomere slender, strongly upturned, as long as 2
nd
palpomere.
Thorax
: Tegula pale orange; thorax pale orange, speckled with dark-brown scales anteriorly. Hind tibia roughly scaled with yellowish- brown setae on inner surface medially; orange white on outer surface. Forewing ground color dark yellowish brown; antemedian band yellowish white, broadened toward costa, width on costa more than twice width on dorsum, postmedian band not developed; costa slightly arched beyond basal 2/3, with small, triangular, orange-white costal patch on 3/4 of costa; apex acute; termen oblique; fringe with narrow, yellowish white basal line, then dark yellowish brown medially, yellowish white in distal half; venation (
Fig. 2C
) similar to that of the
type
species. Hind wing evenly yellowish white; apex more or less obtuse; venation also similar to that of the
type
species.
Abdomen
(
Fig. 2G
): Spinous zones on dorsal surface broadly developed with strong spines; sternite VIII concave antero-medially.
Male genitalia
(
Figs 2
D–F): Uncus slender, heavily sclerotized, slightly bent beyond 4/5, not exceeding apex of basal plate of gnathos, acute apically. Basal plate of gnathos narrowed in distal half; median process short, strongly bent beyond middle, with sharply pointed apex. Tegumen sclerotized, with deeply concave anterior margin. Valva broad basally; costa with basal expansion anteriorly, deeply concave beyond; ventral margin nearly straight, slightly concave before cucullus; sacculus weakly sclerotized, triangular in basal 1/3; cucullus short, densely setose, with rounded outer margin, triangularly produced apically; apex sharply pointed, bent inwardly. Juxta trapezoidal, narrowed distally, with crescent median plate on caudal margin; anterior margin with conic protrusion medially. Aedeagus stout, slightly shorter than valva, gently bent medially; dorsal surface terminated with semi-ovate protrusion, slightly upturned; cornuti consist of a round plate and an irregularly shaped, small plate apically.
Female
